8 THE ENTOMOLOGIST. • 



pterostigma looked rather larger than usual. Both right wings 

 acd the left hind one had a cross-vein on the pterostigma (Neave)- 

 Such a cross-vein seems to be exceptional, and this example had 

 three. The species was taken at Horsley, Surrey, on 8 Oct. 

 (Blair). On 28 June a naiad was taken at Marlborough 

 Deeps in the New Forest, and from it the same evening a female 

 imago emerged. At 7.20 (s.t.) the thorax was noticed partly out ; 

 emergence, however, had but recently commenced. By 7.24 the 

 head and fore legs had emerged, and at 7.25 the mid and hind 

 legs were out. The " rest " then commenced and lasted till 7.59. 

 There was at first during this " rest " a good deal of twitching 

 of legs and lower lip in a somewhat rhythmic manner. During 

 the latter part it became less, the hind and mid legs becoming 

 practically still, fore legs and lip slowing down and becoming 

 still later. During the " rest " the body twitched violently a few 

 times. At the end there was a sudden jerk forwards and speedy 

 extraction of the tip of the abdomen, which was then a little 

 longer than the abdomen of the naiad. The imago — yeliowish- 

 green with browner markings — was now hanging to the empty 

 skin. The wings then began to expand from the base, and 

 during most of the time occupied in the expansion there was a 

 slight (or more pronounced) swaying of the abdomen backwards 

 and forwards. By 8.10 the wings had extended till they were 

 about opposite the tip of the abdominal appendages, but the 

 abdomen had apparently also lengthened a little. The extension 

 of the wings was more rapid towards the end of the period. At 

 8.12 they reached much beyond the tip of the appendages. At 

 8.15 they were about full length and of a beautiful pale yellowish- 

 green colour. The face had by now turned from green to yellow. 

 The abdomen was arched round the margin of the wings. At 

 8.23 the wings were flat and becoming slightly transparent. 

 The abdomen extended but slowly : at 8.32 it was contracting 

 and extending slightly, up and down, but the tip of the appen- 

 dages was still more than half an inch short of the tip of the 

 wings. At 8.45 I had to leave it for about an hour and a half, 

 the abdomen then being not much longer than at 8.32. On my 

 return the abdomen was fully extended. The dragonfly spread 

 its wings in the darkness, and flew off to the window in the 

 morning, the wings then being very glossy. 



On 9 June a brown -winged JEschna flew by at close quarters 

 near Horsley : it could only have been M. grandis, Linn, and if 

 a capture had been made it would have constituted an early date 

 for the species (Lucas). It was taken at Delamere in August 

 (Jackson). On 3 Oct. one was seen flying over the Long Water 

 at Hampton Court, Middlesex (Lucas). 



CALOPTERYGiDiE. — Calopteryx virgo, Linn, was swarming in 

 Alice Holt on 24 May ; " the wood was in parts all alive with 

 them, largely more or less immature " (Stowell). In the New
